RIMMING-MACHINE.

rims that contain a core of stiflening ma terial such as for instance metal wire which is covered with textile fabric. Such rims are found in many instances on the brimsof ladies hats and the stiffening wire is:

covered by the selvage or the outer edge of the goods of which the brim is made. Heretofore such rims were usually made by roll-- ing in the wire by hand which is a lengthy and expensive operation and does not produce a product as uniform as is desirable.

The present'inventlon has'for its purpose to produce such rims by means of a machine which folds the selvage or outer edge of Means .are prothe goods over the wire. vided on the machine for applying a glutinous substance to a short portion of the wireand selvage at a time while the rim is produced. There is further a tucking device for tucking in the edge of the selvage or outer edge of the textile fabric so that said edge is completely pressed closely under the wire whereby a nicely finished rim is 'obtained.

The invention further consists in the construction and arrangement of the details and care has been taken to produce a compact but neat and desirable machine that works quickly and reliably, all as will be fully described hereinafter with reference to the accompanying drawings in which:

Fig. 3 shows in side elevation partly in section the front portion of the machine. Fig. 4 is a like view of the front portion of the machine with certain operative parts in another location.

tion on line 55 of Fig. 3. Fig. 6 is a front view of Figs. 3 and 4, and Fig. 7 is a sectional view of the finished rim.

Similarcharacters of reference denote like parts in all the figures.

In the drawings 1 represents substantial frame work with bearings in its lower portion for a main shaft 2. A cam 3 is mounted on said main shaft having an irregular circular groove 4 around its whole circumference to produce. a to and fro motion in a horizontal plane of certain mechanism. On the main shaft 2 there is further mounted an eccentric 5 having a broad portion 6 to actuate the rim forming mechanism. A small roller 7 travels in the groove 4 of the cam 3. This roller is carried by a support 8 fastened to two parallel shafts 9 and 10 which are movably mounted in the upper portion of the frame 1. The rear end portion of the rod or-shaft 9 supports a vertical member 11 that reaches into a reservoir 12 containing glutinous substance. In the reservoir 12 there is a small force pump 13 which is intermittently operated by means of the vertical member 11 when the rods 9 andlO perform the to and fro motion above referred to. A conduit 14 connects with the force pump 13 which conduit reaches downwardly to the place where the rim is formed and supplies there intermittently small quantities of glutinous substance as required during the operation of the machine. On the front end portions of the two rods 9, 10 there is a vertical supporting member 15 for a tucker 16. The tucker is pivotally secured in the support 15 and extends inwardly in a downwardly slanting direction. The inner end portion of the tucker forms two narrow fingers 17, 18 shown in plan view in Fig. 5. It is evident that when the rods 9 and 10 perform a horizontal to and fro motion by virtue of the movement of the cam roller 7 in the cam groove 4 the tucker will perform a corre sponding to and fro motion. The tucker is normally pressed downward by means of a spring 19. v

The eccentric 5 on the shaft 2 is rotated of course with same and the cam 3. When the eccentric portion is in its upper location a supporting, vertical member 20, shown in its lowest position in Figs. 3 and 4, is

raised. This member 20 is bent twice at a right angle and has formed on its lower second vertical portion a shoe 21 in which two recesses 22 are cut as shown in Fig. 5. Through these recesses pass the fingers 17, 18 of the tucker during the operation of the machine. In Fig. 3 the tucker is shown in its outer position when the rods 9 and 10 have been moved forward while in Fig. 4 the tucker has been moved inwardly by .the returning rods 9 and 10 and the fingers are in the position of starting to tuck in the selvage or outer edge of the textile material of which the rim is formed. When the cocentric 5 revolves and its eccentric portion is in its lowest location the supporting member 20 will go down. In order to insure such downward movement a vertical rod 23 is secured to the horizontal portion of the same. This rod extends into the front top portion of the frame whose lower portion is cut out so as to house partly a coil spring 24: which surrounds the rod 23 and tends to press down the supporting member 20.

Pivoted in the frame 1 there is a folding device 25 which is operated by the eccentric 5. This device consists of two members 26, 27 linked together. The front portion of the member 27 forms a nose so as to pass conveniently over the selvage of the goods. The lower member 26 is normally pressed in an inward direction by a spring 28 shown in Fig. 1. During each revolution of the eccentric 5 this member 26 comes alternately and successively in contact once with the narrow portion of said eccentric and once with its broad portion 6 whereby the folding device performs such to and fro motion as is necessary for the folding of the selvage or outer end portion of the goods over the wire.

The front top portion of the frame 1 supports an upper shoe 29 which has a downwardly extending front portion 30 to the lower end of which is pivoted a small wheel 31. This small wheel travels on a feeding device 32 reaching into a base plate 33. The base plate extends from the inner part of the frame as shown in Fig. 1 and the small roller 31 is provided for the ur ose of reducing the friction when the 'ee ing device moves the goods to be operated upon. This feed is substantially of the same construction as those found in sewing machines.

Sidewise extending from the upper shoe 29 there are two horizontal arms 34., 35. Each arm has integrally therewith a downward extension 36, 37. The extension 36 carries a small sheave 38 while the extension 37 has a bottom end portion that is formed into a wire guide 39. The upper shoe 29 is pivoted to the top front portion of the frame so that it may be lifted when a work piece, say the brim 40 of a ladies hat is to be introduced into the machine. To keep the upper foot normally down a spring 41 is secured to the top frame as shown in Figs. 1,

and i.

The operation of the machine is very simple. First, the upper foot 29 is lifted to introduce the brim of the hat together with the wire which rests on the selvage. Now the main shaft 2 is rotated in any suitable manner whereupon the eccentric will fold the selvage over the wire by virtue of its narrow and wide portion. The eccentric also raises the member 20 and the spring 24: lowers same. Simultaneously the rods 9 and 10 move to and fro by the action of the cam with its irregular groove and the cam roller 7 that is secured to said two rods whereby the force pump is operated to supply intermittently an adhesive and the tucker reciprocated. The feeding device operates in the usual manner. All the described parts are so timed as to cooperate to accomplish the desired result.
